以传统空心面生产工艺为基础,挤压预糊化荞麦粉和高筋粉混合原料,加工冲泡即食非油炸荞麦方便面。考察一次长时间发酵、多次短时间发酵以及压片对面粉粉质特性、面条质构特性和冲泡时复水性以及感官品质等的影响。结果表明,发酵可显著改善冲泡性,压片对面条品质没有影响。通过发酵和预糊化荞麦粉的应用,可以得到冲泡性和口感均较好的非油炸荞麦方便面。  相似文献

参照国际标准分析方法,对挤压空心面的烹煮特性和质构特性进行分析,使用正交试验优化了挤压工艺条件,通过感官评定实验验证了优化工艺条件。结果表明,挤压时的螺杆转速对空心面烹煮时间、烹煮吸水率、烹煮损失率、硬度以及剪切力均有显著影响,而喂料水分含量与喂料速度的影响不显著,因素影响主次顺序为螺杆转速〉喂料速度〉水分含量。当喂料水分含量为28%、喂料速度为20 r/min、螺杆转速为30 Hz时,制成的空心面具有良好的强度和韧性、琥珀色的外观以及优良的烹煮特性和品质特性。  相似文献

Research was conducted to determine the stability of secoisolariciresinol diglucoside (SDG) and α‐linolenic acid (ALA) in flaxseed‐fortified macaroni. Macaroni was fortified with whole ground flaxseed (GWF) at levels of 10% to 20% and then dried under low temperature (LT, 40°C), high temperature (HT, 70°C), or ultrahigh temperature (UHT, 90°C). Macaroni was also fortified with 15% ground hull (GHF) or steam‐treated whole ground flaxseed (GSWF) and dried under UHT. The dried macaroni was stored for 32 wk under ambient conditions. Approximately 80% to 95% of the SDG was recovered, indicating that SDG was stable during the 32‐wk storage period. Total lipid and ALA levels in all flaxseed macaroni treatments remained unchanged throughout the 32‐wk storage. This observation was consistent across the drying conditions and flaxseed addition levels. Conjugated diene (CD) values indicated that macaroni fortified with GWF did not oxidize significantly during the 32‐wk storage for the macaroni dried under HT or UHT. However, a significant increase (P <0.05) in CD values for macaroni containing 10% and 20% flaxseed and dried using LT was observed at the 32‐wk storage period. Headspace volatile concentrations did increase over the storage period for macaroni containing GWF, but the increase was not significant. Significant increases (P < 0.05) in oxidation were found by 24 wk in GHF‐ and GSWF‐fortified macaroni. GWF macaroni dried at UHT, HT, or LT could be used as a way to improve our dietary consumption of ALA and SDG. However, use of steam as a method to inactivate unwanted enzyme activity is not recommended.  相似文献
